Please, identify three ways we use analog and digital signals in our everyday lives.

Sources of analog (continuous) information:

1. Violin. It can create a sound of any height. The transition from tone to tone is smooth and continuous.

2. TV. The kinescope beam moves smoothly and continuously across the screen, and the brightness of individual sections changes smoothly.

3. Phone, the sound Volume changes smoothly and continuously.

Analog information can be turned into digital information (for example, you can assign a number in different colors or write music in notes) and Vice versa.

Explanation:

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
